Description

Botanical classification: Prunus persica var. nucipersica.

Variety denomination: ‘NECTABANG’.

This application claims priority of Community plant variety right No. 2009/0927 filed on May 18, 2009, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Prunus persica var. nucipersica yellow nectarine tree, which has been given the denomination ‘NECTABANG’. This tree, named ‘NECTABANG’, produces clingstone fruits of good eating quality for fresh market in June in the 66—Pyrénées-Orientales departement—France. Contrast is made to ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) and ‘Nectapink’ (U.S. Plant Pat. No. 17,584) yellow nectarine trees, standard varieties, for reliable description. ‘NECTABANG’ is a promising candidate for commercial success in that it has an evenness of maturity, and produces regular fruits in large quantity and with a high productivity. It was chosen because of its hardiness and fruit lifetime before and after harvest, and because of its aromatic semi sweet taste.

ORIGIN OF THE VARIETY

‘NECTABANG’ nectarine tree originated in a cultivated area of the south of France, in the 66—Pyrénées-Orientales departement—France where it was tested. This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontagne’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year, and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘NECTABANG’ variety was selected from controlled crosses between the ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) yellow nectarine tree (female parent) and the ‘Nectapink’ (U.S. Plant Pat. No. 17,584) yellow nectarine tree (male parent). ‘NECTABANG’ is a variety which has a number of flowers smaller than the number of flowers on ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) trees. Moreover, ‘NECTABANG’ fruits are bigger, have a more intense skin colour and a sweeter taste than ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) fruits. Compared to the male parent ‘Nectapink’, (U.S. Plant Pat. No. 17,584) ‘NECTABANG’ variety ripens 45 days earlier and ‘NECTABANG’ fruits are more appealing. ‘NECTABANG’ was provisionally designated, tested and genetically identified by a genetic profile, as 4N.05.141 NJ ASF 0503 and was registered at the Official Catalogue of the Agriculture Ministry of the French Republic on Dec. 1, 2008 under number 1028953. It was obtained by hybridizing and propagated by grafting on a ‘Franc Inra Montclar’ (non-patented) or ‘Cadaman’ (non-patented) or ‘INRA GF 677’ (non-patented) rootstock trees. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of the standard rootstock trees set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées-Orientales, France. More particularly, the plant was reproduced by grafting.

SUMMARY OF THE VARIETY

The new and distinct variety of nectarine tree blooms in March at Perpignan in the Pyrénées-Orientales departement, France. More particularly, it generally blooms between March 1^st and March 10^th, approximately at the same time than the ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) variety.

The first fruit of ‘NECTABANG’ ripens in middle June, generally about one week after the ‘Nectaprima’ (U.S. Plant Pat. No. 17,583) variety. More particularly, it approximately ripens between June 10^th and June 25^th under normal climatic conditions. The fruits of NECTABANG variety ripen about 8 weeks before NECTATOP (U.S. Plant Pat. No. 21,141) fruits and 10 weeks before NECTAPI (U.S. Plant Pat. No. 21,156) fruits. Indeed, NECTATOP and NECTAPI fruits ripen respectively in early August and in early September, whereas NECTABANG fruits ripen in early June.

DESCRIPTION OF THE DRAWINGS

In the accompanying drawing, which are as nearly true as it is reasonably possible to make in a color illustration of this type:

FIG. 1 is a color photograph, which shows typical fruit specimens on a tree of the new variety and leaves of the new variety in orchard.

FIG. 2 is a color photograph, which shows two whole fruit sufficiently mature for harvesting and shipment and five leaves of the new variety.

FIG. 3 is a color photograph, which shows a fruit cut in half for depicting the fruit flesh and the pit cavity of the new variety.

FIG. 4 is a color photograph with reverse and size views of flowers of the new variety, and, with petals removed, reproductive organs of the new variety.

Due to chemical development, processing and printing, the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual botanical specimen.

DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition.

Trees are vigorous and of medium stature, half-standing in a semi-spread to semi-upright out aspect. The anthocyanic coloration of the flowering shoot is present excluding brushwood side away from sun. Flowering begins semi-early in springtime. The type of flower is showy with generally medium to large petals of medium pink color. Leaf glands are present and reniform. Time of maturity for consumption is early. The fruit flesh is yellow with only rare red pigmentation. Fruit skin color features an homogeneous dark red blush. Fruit taste is semi-sweet.

The ‘NECTABANG’ variety blooms almost at the same time and ripens approximately one week after the ‘Nectaprima’ variety (U.S. Plant Pat. No. 17,583). However, the number of flowers on ‘NECTABANG’ trees is smaller than the number of flowers on ‘Nectaprima’ trees (only 40 flowers per meter instead of 50-60 flowers per meter). Compared to ‘Nectaprima’ fruits, ‘NECTABANG’ fruits are more appealing because their skin color is more intense and fruits are bigger and with a sweeter taste. They also have a longer shelf life.

The new variety male parent, which is ‘Nectapink’ (U.S. Plant Pat. No. 17,584), comparatively ripens approximately 45 days after the new variety. ‘NECTABANG’ fruits are more appealing with respect to their general shape and color.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of nectarine tree, the following was observed on trees in their third growing season under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales departement, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘Franc Inra Montclar’ (non-patented) trees or ‘Cadaman’ (non-patented) trees or ‘INRA GF 677’ (non-patented) trees. All major color code designations are by reference to The R.H.S. Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

• Tree:
  • • Size.—Generally — Considered large. The tree size the first year was approximately 250 cm. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current season shoots growth could reach 60 to 80 cm. The tree size from the second year (second and next years) reached a final height of 310 to 330 cm with current season shoots length comprised.
    • Spread.—Approximately 100 cm with a cylindrical shape. The whole orchard was oriented to a central leader organization, with tree lines spaced of 4.0 meters and trees spaced of 1.0 meter in a same tree line. As a result, tree spread was about 100 cm and the orchard contained 2500 trees by hectare.
    • Vigour.—Considered average.
    • Productivity.—Very productive. Fruit set is spaced by thinning to develop the remaining fruit into the desired market sized fruit. The number of the fruit set varies with the prevailing climatic conditions, and cultural practices employed during the bloom period, and is therefore not distinctive of the present variety.
    • Bearer.—Very regular. Fruit set has been heavy during the years of observation and thinning of 1 fruit on 3 was necessary every year.
    • Form.—The ‘NECTABANG’ variety has naturally a semi-spread to semi-upright shape.

• Use: The subject variety ‘NECTABANG’ is considered to be a nectarine tree of the early season of maturity, and which produces aromatic semi-sweet fruit with a high level of sugars and a brix higher than 12 degrees. Fruits are excellent for uncooked consumption, crunchy or at full maturity. Due to their flesh quality, firmness and density, they can also be commercialized as 4^th range product (packed fruit or fruit in bags for example). And they are also useful for both local and very long distance shipping because they have a long shelf life after harvesting, up to 1 month.
• Keeping quality: Remarkable. Fruit stayed a little more than one week on tree before harvest and then, has stored well more than 4 weeks after harvest at 2.0 degree Celsius. They have a slow maturation and a long shelf life both on the tree after growth completion and after harvesting without alteration.
• Shipping quality: Considered very good. Fruits of the new nectarine variety showed minimal bruising of the flesh or skin damage after being subjected to normal harvesting and packing procedures. Its resistance to handling during harvest and packing and its long shelf life without alteration after harvest easily permit 3 to 4 weeks shipping at 2 degrees Celsius.
• Resistance to insects and disease: No particular susceptibilities were noted. Under our climatic conditions, favourable to powdery mildew, and with few treatments, the present variety has not been shown to be very sensitive to powdery mildew, or conservation diseases and decay due to its thick and strong skin. No bacteriostatic substances were applied, and no symptom was observed.

Although the new variety of nectarine tree possesses the described characteristics when grown under the ecological conditions prevailing near the town of Elne, France, it should be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control and horticultural management are to be expected.
